CompTIA A+ Certification Guide for Beginners

What CompTIA A+ covers, how the 220-1201 and 220-1202 exams work, and a step-by-step plan to earn the certification as a complete beginner.
Continue readingPlan your CompTIA A+ Core 2 (220-1202) prep in three phases — operating systems, security and troubleshooting — with a readiness checklist before booking.

Core 2 is the software half of CompTIA A+, and it rewards a different kind of preparation from its hardware-focused sibling. Where Core 1 is learned with a screwdriver, Core 2 — operating systems, security fundamentals, software troubleshooting and operational procedures — is learned at the keyboard, inside settings panels, command lines and security menus. The plan below is organised into three phases by subject weight rather than a rigid calendar, because most Core 2 candidates are fitting study around work or around fresh memories of Core 1, and phases flex better than fixed weeks.
You are most likely here in one of two situations: you have just passed Core 1 and want to finish the credential, or you have booked both exams and are planning the pair. Either way the version rule matters: the current Core 2 exam is 220-1202 (the 220-1102 English exam retired in September 2025), and your two passes must come from the same version series — a 220-1101 Core 1 pass cannot be paired with a 220-1202 Core 2 pass. Check which series your Core 1 belongs to before booking anything. If you have not dealt with the first exam yet, its hardware-and-networking preparation is mapped separately in the Core 1 study plan; this article stays on the software side.
The 220-1202 exam runs to a maximum of 90 questions in 90 minutes, mixing single- and multiple-response multiple choice, drag-and-drop, and performance-based questions. Two numbers deserve attention:
The scope of the exam is defined by the official 220-1202 objectives, downloadable free from comptia.org. Download them before you open any course or book, for two reasons: they are the contract for what can be asked, and the 2025 version refresh (V15) folded in more scripting basics, cloud and remote-troubleshooting content — so materials written for 220-1102 need checking against the current list before you trust them.
Operating systems are the heart of Core 2, and Windows is the heart of the operating systems content. Phase one earns the largest share of your study time — around half of it, whatever total timeline you choose.
Work through, in this order:
The single best study habit for this phase is doing real tasks on a real system. Create user accounts and set their permissions. Partition a spare drive. Configure a firewall rule. If you built a virtual machine during Core 1 prep, it now becomes your Core 2 laboratory: snapshot it, break it, fix it, roll it back. If you did not, install a free hypervisor now — a disposable Windows VM is the ideal place to practise installations and recovery options you would never risk on your daily machine.
Core 2 carries A+'s security content: malware types and removal, social-engineering threats, authentication methods, permissions, encryption basics, and securing workstations, mobile devices and small networks. The V15 revision also strengthened IoT-security coverage, so give connected-device hardening real attention rather than treating it as a footnote.
Two study techniques fit this material:
A realistic scenario to test yourself against: a user reports their browser home page has changed, pop-ups appear constantly, and the machine has slowed down. Can you narrate the full response — identify the likely infection type, quarantine, remediate, schedule scans, educate the user — in the methodical order the objectives describe? If yes, this phase is landing.
Security here is deliberately foundational — enough to secure endpoints, not to run a security operations centre. If the material grabs you, that appetite has a career route: the follow-on exam is covered in the CompTIA Security+ certification guide, typically after Network+.
The remaining content splits into two clusters.
Software troubleshooting applies phases one and two under symptoms: Windows boot failures, application crashes, mobile OS issues, and malware-infection response. Study these as decision trees — symptom, probable causes, ordered diagnostic steps — because that is how the exam frames them, especially in performance-based questions.
Operational procedures is the content candidates most often skip and then regret: documentation, ticketing, change management, backup types and schedules, safety and environmental controls, privacy and licensing concepts, communication and professionalism. None of it is hard; all of it is easily-dropped marks if unstudied. It also includes the scripting basics the current version emphasises — recognising script file types and reading simple script logic, not writing production code. Budget a focused block for this cluster and it repays a disproportionate number of marks.
However long your phases took, the last stage is the same: stop learning, start measuring. Move through three levels of question practice:
Book the 220-1202 exam when you can honestly tick all of these:
If one box stays unticked, that is your restudy target — a far cheaper discovery now than in the exam room. And if the worst happens on the day, the retake terms are forgiving: no waiting period before a second attempt, 14 calendar days before a third or later, each attempt at full voucher price unless you bought a retake bundle. Why candidates typically fail A+ — and how failure differs between the two cores — is examined in How hard is the CompTIA A+ exam?
Passing Core 2 alongside Core 1 awards the CompTIA A+ credential — the exam code never appears in the certification name. It is valid for three years from your certification date, renewable through CompTIA's Continuing Education programme: 20 continuing-education units, a CertMaster CE course, or passing a higher-level CompTIA exam, which renews A+ automatically.
That last option is worth planning around, because for most people Core 2 is not an endpoint but the moment the credential starts working: applications for help desk and desktop support roles, and a decision about which specialism to build towards next. The branching options — networking, security, cloud, systems — are mapped in the CompTIA A+ career path guide. Finish the exam first; but finish it knowing where the path continues.
As soon as is practical, yes. The exams share a version series, your study routine is already established, and Core 1's networking knowledge feeds Core 2's troubleshooting scenarios. A gap of weeks is helpful for rest; a gap of many months usually means relearning habits — and risks your Core 1 version series approaching retirement before you complete the pair.
They are difficult in different ways: Core 2 demands a higher passing score (700 against 675) and more memorised procedure, while Core 1 punishes weak hands-on hardware knowledge. Candidates from desktop-support backgrounds often find Core 2 more natural; self-taught hardware enthusiasts often find it harder than expected, mostly because of the operational-procedures and security content.
As a supplement, cautiously. The fundamentals overlap substantially, but the current version added scripting, cloud, IoT-security and remote-troubleshooting emphasis that older materials underweight. Reconcile any 1102-era resource against the official 220-1202 objectives and fill the gaps from current sources.
No — CompTIA lets you sit Core 1 and Core 2 in any order, on any dates, provided both passes come from the same version series. Core 1 first is the common route, but a candidate stronger in software than hardware can reasonably reverse it.
